组合导航系统模拟器中的卡尔曼滤波设计

Kalman Filter for the Simulator of Integrated Navigation System

组合导航系统模拟器是飞行训练模拟系统的关键部件,在分别设计了惯性导航系统模拟器以及卫星导航模拟器的基础上,为了提高模拟器的真实性,针对如何实现两个系统最优组合,为其它系统提供准确可靠的导航数据的问题,参照现代飞机组合导航系统的组成结构及工作原理,设计了组合导航卡尔曼滤波器,建立了松组合和紧组合两种组合导航方式的方程和量测方程,并与纯惯性导航系统的结果进行对比分析,证明了所设计的组合导航系统卡尔曼滤波器的有效性。

Simulator of integrated navigation system is very important in the trainer system of flight, in order to improve the reality of the simulator, considering the construct and principle of the integrated navigation system of modern aircraft, based on the designing of inertial navigation system simulator and satellite navigation system, a kalman filter for the integrated navigation is designed, to optimally integrate the two kind of navigation system, supply accurate and reliable for other system, system equation and measurement equation for loose coupled and tightly coupled integrated are designed respectively, comparison and analysis have been done via the pure inertial navigation system to improve the efficiency of the designed Kalman filter for the integrated navigation system.
